WebSep 29, 2014 · K has a more exothermic electron affinity because the electron gained fills the 4s orbital. In Ca the electron goes to 3d. The energy gap between 4s and 3d is enough to make the process barely exothermic. Note that the numbers given in tables are positive but that the process is exothermic. Share Improve this answer Follow WebNov 26, 2024 · Superhalogens are molecules that have electron affinities (EA) greater than that of Cl, the element with the highest EA (3.62 eV). It is well known that noble gases have closed electronic shell structure and hence have high ionization potentials and low electron affinities, due to which they are chemically inert and resistant to salt formation ... egyptian ethiopian war https://allproindustrial.net

Difference Between Electronegativity and Electron Affinity

WebThe greater the distance, the less the attraction and so the less energy is released as electron affinity. Note: Comparing fluorine and chlorine isn't ideal, because fluorine breaks the trend in the group. However, comparing chlorine and bromine, say, makes things seem more difficult because of the more complicated electronic structures ... WebNov 20, 2024 · Electron affinity can be either positive or negative value. The greater the negative value, the more stable the anion is. Although affinity varies greatly across the periodic table, some patterns emerge. Generally, the elements on the right side of the periodic table will have large negative electron affinity.

WebWhich Element Has the Highest Electron Affinity? Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, … WebAs we have seen, the first electron affinity can be greater than or equal to zero or negative, depending on the electron configuration of the atom. In contrast, the second electron affinity is always positive because the increased electron–electron repulsions in a dianion are far greater than the attraction of the nucleus for the extra ...

WebThe electron affinity of an atom or molecule is the propensity for that particle to gain an electron. This is an exothermic process for all non-noble gas elements. There are general trends in electron affinity across and down the periodic table of elements. WebThe electron affinity of sulphur is -200 kJ/mol. Then the electron affinity of oxygen is : Q.
